Why the close matters
The closing line is the market's last and best estimate, because it has absorbed every injury report, lineup change, weather update and dollar bet into the game. That makes it the standard benchmark for judging whether a bet was good, independent of whether it happened to win.
Beating the close
Getting a better number than the closing line is the clearest evidence of an edge available to a bettor. It is measured in percentage points of probability rather than in wins, and it becomes meaningful over hundreds of bets rather than a handful.

Frequently asked questions
What is the closing line?+
The closing line is the final price on a market before the event begins. It reflects all available information and all the money bet into the game, which makes it the market's sharpest estimate.
Why is beating the closing line important?+
Because it scores your decision at the moment you made it, rather than waiting on results that are mostly noise in the short run. Consistently getting better numbers than the close is the strongest leading indicator of long-run profit.
